Real time activity feed that updates the old activities

Is there a plugin that anyone knows or a coding way that I would be able to display the buddypress activity feed which be able to update itself? I mean, now when someone at my website do action like update a post, the activity feed record this action, but if this user change the topic / date of this post or even if the user change his profile name / image – the activity feed still display the old record.
I understand how it works like record the activity to a place to the DB and just print it, but does someone knows another different way to display a real time feed that updates the old feed?

Currently there is no such plugin. Introducing this feature is quite heavy for the server, so it’s more like a custom solution, ideally with websockets.

We use heartbeat functionality, that gives ability to show a notification about new activity records, but there are no plans to actually update old records due to lots of technical issues and time availability (all BuddyPress core devs are volunteers).
